Magnetospheric processes in the plasmapause

Eos, Transactions American Geophysical Union, 1984
The current experimental and theoretical status on the existence and importance of the plasmapause as a magnetospheric boundary was the subject of a conference on Fundamental Magnetospheric Processes in the Plasmapause Region, held at Huntsville, Ala., October 25–27, 1983, under the joint sponsorship of the Marshall Space Flight Center and the ...

Narrow-band emission with 0.5 to 3.5 Hz varying frequency in the background of the main phase of the 17 March 2013 magnetic storm

Solar-Terrestrial Physics, 2016
We present results of the analysis of an unusually long narrow-band emission in the Pc1 range with increasing carrier frequency. The event was observed against the background of the main phase of a strong magnetic storm caused by arrival of a high-speed ...

The Evolution of Whistler Hiss‐Like Waves Across Plasmapause: Hiss to Exohiss

Geophysical Research Letters, 2023
The exohiss waves are hiss‐like whistler mode waves that occur outside plasmapause. Although these waves can cause the loss of radiation belt electrons ∼

A new model for plasmapause locations derived from IMAGE RPI and Van Allen Probes data

Journal of Space Weather and Space Climate
The outer boundary of the plasmasphere, the plasmapause, is characterized by a sharp electron density gradient that changes under varying space weather conditions.

Ionospheric Pc1 waves during a storm recovery phase observed by the China Seismo-Electromagnetic Satellite [PDF]

Annales Geophysicae, 2020
During the storm recovery phase on 27 August 2018, the China Seismo-Electromagnetic Satellite (CSES) detected Pc1 wave activities in both the Northern Hemisphere and Southern Hemisphere in the high-latitude, post-midnight ionosphere with a central ...

Global Plasmaspheric Refilling Rates Inferred From Deep‐Learning Electron Density Reconstructions

Geophysical Research Letters, Volume 53, Issue 16, 28 August 2026.
Abstract As a key process in magnetosphere‐ionosphere coupling, plasmaspheric refilling is a long‐standing focus in space physics. In this study, we develop a global electron density (GEO‐NE) model based on a CNN‐Transformer architecture, and use the model to investigate plasmaspheric electron density refilling rates. Using global electron density maps

Cluster observations of mid-latitude hiss near the plasmapause [PDF]

Annales Geophysicae, 2004
In the vicinity of the plasmapause, around the geomagnetic equator, the four Cluster satellites often observe banded hiss-like electromagnetic emissions (BHE); below the electron gyrofrequency but above the lower hybrid resonance, from 2kHz to 10kHz ...

Excitation of Large Amplitude Compressional ULF Waves in the Magnetosphere by Solar Wind Pressure Spikes and IMF Southward Turning

Journal of Geophysical Research: Space Physics, Volume 131, Issue 8, August 2026.
Abstract We present a case study of large amplitude, compressional Pc5 waves observed by GOES 13 and 15 at geosynchronous orbit near noon. These waves were excited near the arrival time of two consecutive solar wind dynamic pressure spikes at the magnetopause, the second of which was associated with a large and rapid southward turning of the ...

Correlations between plasmapause evolutions and auroral signatures during substorms observed by Chang’e-3 EUV Camera

Earth and Planetary Physics, 2017
The plasmapause locations determined from the Chang’e-3 (CE-3) Extreme Ultraviolet Camera (EUVC) images and the auroral boundaries determined from the Defense Meteorological Satellite Program (DMSP) Special Sensor Ultraviolet Spectrographic Imager (SSUSI)
